Title: Improvements in carburetters for internal combustion engines
IPC: F02M1/00
Filed: 1931-03-12
Abstract: 374,509. Spray carburetters. SVENSKA ACKUMULATOR AKTIEBOLAGET JUNGNER, 17, Riddaregatan, Stockholm. March 12, 1931, No. 7637. Convention date, March 13, 1930. [Class 7 (iii).] In carburetters having a fuel pump actuated from the throttle valve to facilitate acceleration, the fuel passage from the pump to the induction pipe is provided with a fuel receiving space open to atmosphere and so disposed that fuel will be supplied to the induction pipe upon quick opening movement of the throttle. The induction pipe 1 has a narrow fuel outlet 4 formed between rings 2, 3. An additional fuel passage 5 is connected by conduit 6 to the chamber 7 of a pump having a piston 10 provided with valve 12 and connected by the rod 9 and arm 16 to the throttle valve spindle 17. The upper part of the pump cylinder forms the fuel receiving space 19 which is open to atmosphere at 20, and communicates at 22 with, and in part interrupts, the additional fuel passage 5, 6. For slow throttle movements, most of the additional fuel enters space 19 and ultimately overflows the upper edge of a bush 18 and returns to the pump. For quick throttle movements, however, the fuel takes the form of a jet and is forced past the aperture 22 to the outlet 4. Fuel remaining in space 19 is ultimately sucked out through aperture 22. In the lowest position of the pump piston, a needle valve 23 is opened and further additional fuel is supplied through the duct 25. The normal supply to outlet 4 is through a conduit from the float chamber, such, for example, as described in Specification 353,466. Fuel enters the pump by conduit 21, the normal level is at n; and the aperture 22 is situated at a lower level than the highest part of conduit 6 which itself is a relatively great distance above the level n. The additional fuel may be introduced at points other than the outlet 4.

Filed: 1943-05-26
Abstract: 599,672. Wireless transmission systems. SPERRY GYROSCOPE CO., Inc. May 26, 1943, No. 8448. Convention date, May 27, 1942. [Classes 40 (iii) and 40 (v)] A constant high-frequency source is coupled to a load circuit by a cavity resonator, the natural frequency of which, and hence the coupling between the source And the load, is recurrently varied during a part of an iterated cycle by rotatable means co-operating with the resonator, the resonator being maintained by the rotatable means during the remainder of each cycle at a constant frequency. As applied to a glidepath system operating with overlapping, alternately radiated beams modulated at different frequencies, cylindrical resonators 4, 5 are coupled by loops 28, 29 and a coaxial line 2 to a high-frequency source, and by loops 30, 31 and coaxial lines 10, 13 to the respective dipole radiators. Discs 8, 9, mounted on the same motor-rotated shaft (not shown), pass through slots in the resonator walls, their peripheries being adjacent the ends of conducting studs 18, 19 in the resonators and being of the forms shown in Figs. 7, 8. As the serrated half 51, 56 of the periphery of each disc passes the end of the corresponding stud the tuning of the resonator is varied, causing an audio-frequency modulation of the energy supplied to the transmitter, of different frequencies in the two cases. The remaining halves 50, 55 of the peripheries are of constant radius, and as they alternately pass the corresponding studs they de-tune the resonators so that each beam alternately is substantially shut off. The coupling loops 30, 31 may be rotated to equalize the outputs to the two radiators, and the resonators may be tuned by angular adjustment of cylindrical plugs (not shown) carrying fins or loops projecting into the resonator chambers. Specifications 523,712, 581,734 and 599,700 are referred to.

Abstract: 747,984. Hydraulic mining. DAWSON, A. S. March 23. 1954 [March 31, 1953], No. 8512/54. Class 68(1) Water-soluble ore is removed from an underground ore bed by first forming a main passage 2 through the ore bed from the foot of a shaft 1, extending from the bottom of the ore bed to the surface, then forming a plurality of secondary passages 3 transverse of and at intervals along the passage 2. and finally dissolving out part of each block of ore between adjacent. secondary passages 3 by passing water through the block. To permit of the entry of water into and the withdrawal of brine but of each block either a hole 5 is drilled betwseen adjacent passages 3 completely through the block, or a pair of intersecting holes are formed in the block from the same passage 3, and a pipe 6 is inserted for a substantial distance into, and sealed within, each end of the bore so formed. The height of the cavity 7 formed within each block is controlled by introducing into the cavity a fluid, which is a non-solvent in respect of the ore and is lighter and immisable with the brine, to form a layer between the brine and the roof of the cavity. Electrodes, situated in the block at the boundary zone to which the cavity be ing formed therein may be safely enlarged, are electrically connected to currentresponsive alarm means. The brine from all the cavities. may drain into a sump at. a level below that of the passages 2 and 3.
